As shown in fig. 3, after the paper board is pushed into the printing mechanism 2 by the feeding block 31, the feeding block 31 needs to move in a direction away from the printing mechanism 2, at this time, the upper end of the feeding block 31 contacts with the lower end of the paper board, so that a friction force away from the printing mechanism 2 is applied to the paper board, which causes the paper board to move, and the feeding block 31 cannot abut against the side wall of the paper board during feeding, thereby affecting the transportation of the paper board. Therefore, the position of the upper end of the feeding plate 11 far away from the feeding block 31 is connected with the limiting block 13 by using a bolt, the end face of the limiting block 13 close to the feeding block 31 is provided with a supporting groove 131, the supporting block 14 is connected in the supporting groove 131 in a sliding manner, the upper end of the supporting block 14 can be abutted against the lower end of the paper board at the upper end of the pushed paper board, and the side wall of the supporting block 14 close to the printing mechanism 2 can be abutted against the side wall of the feeding block 31 far. A plurality of springs 15 for driving the supporting block 14 to move towards the printing mechanism 2 are arranged in the supporting groove 131, one end of each spring 15 is abutted against the side wall of the supporting groove 131 towards the printing mechanism 2, and the other end of each spring 15 is abutted against the side wall of the supporting block 14 far away from the printing mechanism 2.

The position of the paper board is limited by the limiting block 13, so that the paper board cannot move, and the supporting block 14 is used for supporting the paper board, so that the pressure on the moved paper board in the paper board moving process is reduced, the friction between the paper board and the feeding plate 11 is reduced, and the paper board moving process is more convenient.

To further reduce the friction between the cardboard and the upper plate 11, the movement of the cardboard is made faster. As shown in fig. 1, a plurality of rotating rollers 16 are rotatably connected to the upper end of the feeding plate 11, and the rotating rollers 16 are respectively located at both sides of the driving groove 111 and have axes parallel to the printing roller 21. The sliding friction between the paper board and the feeding plate 11 is converted into rolling friction by the rotating roller 16, so that the friction force between the paper board and the feeding plate 11 is reduced, and the paper board moves more smoothly.

As shown in fig. 3, when the paper board is pushed by the upper block 31 to move, the supporting block 14 moves toward the printing mechanism 2 under the pushing of the spring 15, and at this time, the end surface of the supporting block 14 facing the printing mechanism 2 abuts against the paper board, so that the supporting block cannot move to the lower end of the paper board, and the paper board cannot be supported. Therefore, the upper end of the end surface of the supporting block 14 close to the printing mechanism 2 is provided with a wedge surface 141, and the upper end of the wedge surface 141 inclines towards the direction far away from the printing mechanism 2. The wedge-shaped surface 141 pair is used to reduce the area of the support block 14 facing the printing mechanism 2, thereby making it easier for the printing mechanism 2 to be inserted into the lower end of the sheet.

As shown in fig. 1, due to the large number of stacked paper boards, the paper board located above moves in the process of moving downwards, so that the position of the paper board entering the printing mechanism 2 changes, the offset of the sublimation printed on the surface of the paper board occurs, and the printing of the paper board is not qualified. Therefore, the end face of the baffle 12 far away from the printing mechanism 2 is connected with two guide blocks 311, the side walls of the two guide blocks 311 which are close to each other can be respectively abutted against the two side walls of the paper board, and the side walls which are close to each other are all penetrated with a sliding groove which penetrates through the lower end of the guide block. The position of the paper board is limited by the guide block 311, so that the position of the paper board is not changed, and the printing effect is stable.

As shown in fig. 2, since the projected areas of different paper sheets are different, the distance between the two guide blocks 311 needs to be adjusted, so that different paper sheets can be guided. Therefore, two horizontally arranged waist-shaped grooves 122 penetrate through the end surface of the baffle plate 12 close to the printing mechanism 2, two adjusting bolts 18 penetrate through the waist-shaped grooves 122, and the adjusting bolts 18 penetrate through the waist-shaped grooves 122 and are respectively in threaded connection with the end surface of the guide block 311 close to the printing mechanism 2. The distance between the two guide plates 17 is adjusted by the adjusting bolt 18, so that different paper plates can be limited.

As shown in fig. 3, since the contact area between the upper block 31 and the paperboard is small, the contact position between the paperboard and the upper block 31 is deformed during the process of pushing the paperboard by the upper block 31, which affects the quality of the printed paperboard. Therefore, the rectangular feeding rods 33 are welded on the side walls of the feeding blocks 31 perpendicular to the printing roller 21, the side walls of the feeding rods 33 close to the printing mechanism 2 can be abutted against the side walls of the paper boards far away from the printing mechanism 2, and the feeding rods can be arranged in the sliding grooves to slide. The contact area between the paperboard and the feeding block 31 is increased by the feeding rod 33, so that the pressure on the paperboard is reduced, and the deformation of the paperboard is reduced.

The working principle is as follows:

in operation, the paper boards are stacked and placed between the two guide blocks 311, then the printing motor 23 and the feeding motor are started simultaneously, the motor drives the rotating disc 321 to rotate, so that the feeding block 31 moves back and forth, the paper boards contacted with the feeding block 31 move towards the printing mechanism 2 through the feeding hole 121, the supporting block 14 moves towards the printing mechanism 2 under the action of elastic force exerted by the spring 15 when the paper boards move, so that the paper boards which are not moved are supported, when the paper boards are contacted with the printing roller 21, the paper boards are driven to move simultaneously by the printing roller 21 and the fixed roller, and patterns are printed on the surfaces of the paper boards by the printing roller 21. Then the loading block 31 moves towards the supporting block 14, and the supporting block 14 is pushed towards the supporting groove 131 to enter the supporting groove 131, at this time, the stacked paper boards move downwards to abut against the upper end of the loading plate 11, and then loading can be continued.
